It's one of the things being developed on the down low right now, but you can find PRs like:

https://github.com/JuliaLang/julia/pull/24473

which are making this:

https://github.com/JuliaLang/julia/blob/master/src/interpret...

a compilation-free version of Julia. At the same people there is discussion about how to cache native compilation results after precompilation, so that way packages can store all of their compiled code and users can directly use it without compilation through the interpreter. This second part isn't done yet, but it'll be interesting to see what happens when it has a truly dynamic + precompiled form.
